ANN ARBOR -- Trey Burke and Tim Hardaway Jr. are leaving school early for a shot at the NBA.

But, according to coach John Beilein, they've both told him they'd return to school -- at some point -- to finish their college degrees.

"(Hardaway's) less than a year from graduating," Beilein said Wednesday after the junior guard announced he, too, would be leaving the program for the NBA draft. "Both guys have promised me they'll come back in some way, shape or form and graduate.

"They're both in great academic standing."

Burke and Hardaway make four players to leave school early for a shot at the NBA draft during Beilein's time in Ann Arbor.

Former guard Manny Harris left after his junior year in 2010, while former point guard Darius Morris left after his sophomore season in 2011.

As far as graduations go, Beilein said earlier in the week that all five Michigan seniors -- Corey Person, Josh Bartelstein, Matt Vogrich, Blake McLimans and Eso Akunne -- are on track to graduate this spring.

Fourth-year junior Jordan Morgan is also on schedule to graduate.

"I have one more year (of school left), so I'm close," Hardaway said.

Both players said they intended on remaining in Ann Arbor for the rest of the academic semester before departing to train for the NBA draft.
